92

I've never shot the current issue handgun of the US Military.  I need to remedy that.  Or at least familiarize myself with it's feature and how to field strip it.  That can be done with some research.

When I was in the Navy, the issue handgun was the Beretta 92 (aka M9, aka a lot of other variants of same...), but the Navy wasn't on the top of the list for the new pistol so we made do with M1911A1s.  That's what I qualified on.  I am pretty familiar with the 1911 at this point.

It looks simple enough.  DA/SA, safety-decocker looks ambidestrous.  The slide release and takedown lever thingy look ordinary and straight forward.  15 round magazines

Magazine safety?  Can it fire with a round in the chamber but no magazine present?  Dunno.

Field stripping... well, I can't figure that out unless I have one.  But it looks easy.  I'd just have to pay attention when taking it down to be sure I'd put stuff back in facing the correct direction.  Look like 4 parts aside from the frame.  Barrel, slide, guiderod, and spring.  Easy enough.
